Cat Hypercalcaemia and Kidney Disease Welfare

Chronic kidney disease is the leading cause of death in older cats, and its management through appropriate nutrition and veterinary care significantly affects welfare outcomes.

Key Facts

Chronic kidney disease affects approximately 30-40% of cats over 10 years
Early diagnosis through annual blood and urine testing enables earlier intervention
Prescription renal diets slow progression and improve quality of life
Subcutaneous fluid administration at home can be learned by owners
Euthanasia decisions should be based on quality of life assessment rather than biochemical values alone

Welfare Considerations

CKD causes nausea, reduced appetite, lethargy, and increased water intake that progressively worsen without management. Early detection through regular screening allows dietary and medical intervention that slows progression and maintains quality of life. Quality of life assessment using validated tools helps owners and vets make appropriate management and end-of-life decisions based on the cat's experience rather than laboratory results alone.

What You Can Do

Screen cats over eight years annually for kidney disease
Begin renal dietary management at the earliest stage when palatable to the cat
Learn to administer subcutaneous fluids at home if your vet recommends it
Use quality of life assessment tools to guide management decisions
Discuss palliative care options with your vet before a crisis develops
